David Kerkmann has been competing for 17 years. His best event is the 2×2: a personal-best single of 2.22, set at German Open 2011, puts him in the top 6.4% of the 189,179 people who have ever been ranked in the event, and 261st in Germany. Until February 2008, no official 2×2 solve in the world had been that fast. Across 12 competitions since November 2009, he has put 282 official solves on the record across seven events.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
